Formulations

Useful formulations of the compounds of Formula I can be prepared in conventional ways. They include dusts, granules, pellets, solutions, suspensions, emulsions, wettable powders, emulsifiable concentrates and the like. Many of these may be applied directly. Sprayable formulations can be extended in suitable media and used at spray volumes of from a few liters to several hundred liters per hectare. High strength compositions are primarily used as intermediates for further formulation. The formulations, broadly, contain about 0.1% to 99% by weight of active ingredient(s) and at least one of (a) about 0.1% to 20% surfactant(s) and (b) about 1% to 99.9% solid or liquid inert diluent(s). More specifically, they will contain these ingredients in the following approximate proportions:

Lower or higher levels of active ingredient can, of course, be present depending on the intended use and the physical properties of the compound. Higher ratios of surfactant to active ingredient are sometimes desirable, and are achieved by incorporation into the formulation or by tank mixing.

Typical solid diluents are described in Watkins, et al., "Handbook of Insecticide Dust Diluents and Carriers", 2nd Ed., Dorland Books, Caldwell, N.J., but other solids, either mined or manufactured, may be used. The more absorptive diluents are preferred for wettable powders and the denser ones for dusts. Typical liquid diluents and solvents are described in Marsden, "Solvents Guide," 2nd Ed., Interscience, New York, 1950. Solubility under 0.1% is preferred for suspension concentrates; solution concentrates are preferably stable against phase separation at 0° C. "McCutcheon's Detergents and Emulsifiers Annual", MC Publishing Corp., Ridgewood, N.J., as well as Sisely and Wood, "Encyclopedia of Surface Active Agents", Chemical Publishing Co., Inc., New York, 1964, list surfactants and recommended uses. All formulations can contain minor amounts of additives to reduce foaming, caking, corrosion, microbiological growth, etc.

The methods of making such compositions are well known. Solutions are prepared by simply mixing the ingredients. Fine solid compositions are made by blending and, usually, grinding as in a hammer or fluid energy mill. Suspensions are prepared by wet milling (see, for example, Littler, U.S. Pat. No. 3,060,084). Granules and pellets may be made by spraying the active material upon performed granular carriers or by agglomeration techniques. See J. E. Browning, "Agglomeration", Chemical Engineering, Dec. 4, 1967, pp. 147ff. and "Perry's Chemical Engineer's Handbook", 5th Ed., McGraw-Hill, New York, 1973, pp. 8-57ff.

Utility

Test results indicate that the compounds of the present invention are active herbicides. They should have utility for broad-spectrum pre- and/or post-emergence weed control in areas where complete control of all vegetation is desired, such as around fuel storage tanks, ammunition depots, industrial storage areas, parking lots, drive-in theaters, around billboards, highway and railroad structures.

The rates of application for the compounds of the invention are determined by a number of factors, including the types of weeds to be controlled, weather and climate, formulations selected, mode of application, amount of foliage present, etc. In general terms, the subject compounds should be applied at levels of around 0.01 to 10 kg/ha, the lower rates being suggested for use on lighter soils and/or those having a low organic matter content, or for situations where only short-term persistence is required.

The compounds of the invention may be used in combination with any other commercial herbicide; examples of which are those of the triazine, triazole, uracil, urea, amide, diphenylether, carbamate, and bipyridylium types.

The herbicidal properties of the subject compounds were discovered in a number of greenhouse tests. The test procedures and results follow. ##STR360##

Test A

Seeds of crabgrass (Digitaria spp.), barnyardgrass (Echinochloa crusgalli), wild oats (Avena fatua), sicklepod (Cassia obtusifolia), morningglory (Ipomoea spp.), cocklebur (Xanthium pensylvanicum), sorghum, corn, soybean, sugar beet, rice, wheat, and purple nutsedge (Cyperus rotundus) tubers were planted and treated pre-emergence with the test chemicals dissolved in a non-phytotoxic solvent. At the same time, these crop and weed species, along with cotton and bush bean, were treated with a soil/foilage application. At the time of treatment, the plants ranged in height from 2 to 18 cm. Treated plants and controls were maintained in a greenhouse for sixteen days, after which all species were compared to controls and visually rated for response to treatment. The ratings, summarized in Table A, are based on a numerical scale extending from 0=no injury, to 10=complete kill. The accompanying descriptive symbols have the following meanings:

C=chlorosis/necrosis;

D=defoliation;

E=emergence inhibition;

G=growth retardation;

H=formative effect;

U=unusual pigmentation; and

6Y=abscised buds or flowers.

Test B

Two plastic bulb pans were filled with fertilized and limed Fallsington silt loam soil. One pan was planted with corn, sorghum, Kentucky bluegrass and several grass weeds. The other pan was planted with cotton, soybeans, purple nutsedge (Cyperus rotundus), and several broadleaf weeds. The following grass and broadleaf weeds were planted: crabgrass (Digitaria sanguinalis), barnyardgrass (Echinochloa crusgalli), wild oats (Avena fatua), johnsongrass (Sorghum halepense), dallisgrass (Pasapalum dilatatum), giant foxtail (Setaria faberii), cheatgrass (Bromus secalinus), mustard (Brassica arvensis), cocklebur (Xanthium pensylvanicum), morningglory (Ipomoea hederacea) sicklepod (Cassia tora), teaweed (Sida spinosa), velvetleaf (Abutilon theophrasti) and jimsonweed (Datura stramonium). A 12.5 cm diameter plastic pot was also filled with prepared soil and planted with rice and wheat. Another 12.5 cm pot was planted with sugar beets. The above four containers were treated pre-emergence with several test compounds within the scope of the invention.

Twenty-eight days after treatment, the plants were evaluated and visually rated for response to the chemical treatments utilizing the rating system described previously for Test A. The data are summarized in Table B.

Test C

The test chemical, dissolved in a non-phytotoxic solvent, was applied in an overall spray to the foliage and surrounding soil of selected plant species. One day after treatment, plants were checked for rapid burn injury. Approximately fourteen days after treatment all species were visually compared to untreated controls and rated for response to treatment. The rating system was as described previously for Test A. The data are presented in Table C.

All plant species were seeded in Woodstown sandy loam soil and grown in a greenhouse. The following species were grown in soil contained in plastic pots (25 cm diameter by 13 cm deep): soybeans, cotton, bush bean, corn, rice, wheat, sorghum, velvetleaf (Abutilon theophrasti), sesbania (Sesbania exaltata), sicklepod (Cassia obtusifolia), morningglory (Ipomoea hederacea), jimsonweed (Datura stramonium), cocklebur (Xanthium pensylvanicum), crabgrass (Digitaria spp.), nutsedge (Cyperus rotundus), barnyardgrass (i Echinochloa crusgalli), giant foxtail (Setaria faberii), and wild oats (Avena fatua). Sunflower and mustard were grown in soil in a paper cup (12 cm diameter by 13 cm deep). Additional plant species, such as johnsongrass and field bindweed are sometimes added to this standard test in order to evaluate unusual selectivity. All plants were sprayed approximately 14 days after planting.

The data show that the compound selected for this test possesses high post-emergence activity.

Test D Postemergence

Two round pans (25 cm diameter by 12.5 cm deep) were filled with Sassafras sandy loam soil. One pan was planted with blackgrass, sugar beets, nutsedge (Cyperus rotundus) tubers, crabgrass (Digitaria sanguinalis), sicklepod (Cassia obtusifolia), teaweed (Sida spinosa), jimsonweed (Datura stramonium), velvetleaf (Abutilon theophrasti), and giant foxtail (Setaria faberii). The other pan was planted with wheat, cotton, rice, corn, soybean, wild oats (Avena fatua), cocklebur (Xantium pensylvanicum), morningglory (Ipomoea hederacea), johnsongrass (Sorghum halepense) and barnyardgrass (Echinochloa crusgalli). The plants were grown for approximately fourteen days, then sprayed post-emergence with the chemicals dissolved in a non-phytotoxic solvent.

Test E

Two plastic pans lined with polyethylene liners were filled with prepared Woodstown sandy loam soil. One pan was planted with seeds of wheat (Triticum aestivum), barley (Hordeum vulgare), wild oats (Avena fatua), cheatgrass (Bromus secalinus), blackgrass (Alopecurus myosuroides), annual bluegrass (Poa annua), green foxtail (Setaria viridis), Italian ryegrass (Lolium multiflorum) and rapeseed (Brassica napus). The other pan was planted with seeds of Russian thistle (Salsola kali), cleavers (Galium aparine) speedwell (Veronica persica), kochia (Kochia scoparia), shepherd's purse (Capsella bursa-pastoris), Matricaria inodora, black nightshade (Solanum nigrum), wild buckwheat (Polygonum convolvulus), and sugar beets (Beta vulgaris). The above two pans were treated pre-emergence. At the same time two pans in which the above plant species were growing were treated post-emergence. Plant height at the time of treatment ranged from 1-20 cm depending on plant species.

The compounds applied were diluted with a nonphytotoxic solvent and sprayed over-the-top of the pans. An untreated control and a solvent alone control were included for comparison. All treatments were maintained in the greenhouse for 19-22 days at which time the treatments were compared to the controls and the effects visually rated. The recorded data are presented in Table E.
